London, Oct 19 (TIWN) For the first time in 37 years, the UK Parliament will on Saturday to participate in what is being deemed as a "knife-edge" vote on Prime Minister's Boris Johnson's latest Brexit deal, a last attempt before the October 31 deadline to leave the European Union (EU).

Crucial day for Brexit: Lawmakers will hold a rare Saturday parliamentary sitting to debate the Prime Minister's Brexit deal and hold a crucial vote. Will he win? It's touch and go whether Boris Johnson has the numbers to win: the Northern Irish Democratic Unionist says it will not back his deal, but several former Conservative Party rebels and Labour lawmakers have indicated they will support it.
